Take off: 16:36:50 16:42 changed to 45 min calint 16:57~ changed to 90/690 setpoints 17:13 Only now closed InletPurge green on/off valve 17:40-realize that MED_PSA and MEDPBY are reversed at the rack to DSM twinax outs 18:02:36 Changed to 180/400 PSetpoints 18:23~ medflow dropped from 18:50 hit sample to sample flask 10, and system returned to PrePurge mode for 10-15 secs also occurs for subsequent flask samples. Appears to have to do with setting prepurge to 30 just before flight when it expected 45. May have happened for earlier samples, but Andy and I didn't notice. 18:55 or so AEROS crashes 19:02 AEROS crashes a second time 20:33:00-20:34:00 AO2 inlet breathtest TAKING TEMPERATURE MEASUREMENTS AROUND MEDUSA RACK 0cm: 8.6C (base of Box 1, front) 0cm: 9.5 (base of box 1, back) 50cm: 14.1C (top of Box 1) 50cm: 14.3 (top of box1, back) 65cm: 20.2 (bottom of box 2, front) 65cm: 20.3 (bottom of box 2, back behind laptop) 100cm: 21.6 (top of box 2, front) 100cm: 19.7 (top of box 2, back above laptop) 20:45:35ish Huge spike in AO2CO2 for about 5-10 secs. Reminiscent of problem like this in HIPPO3. 20:50~ Noticed that O2 volts are climbing higher and higher again, like in HIPPO3, and are just below 10--9.99ish. 21:22 Noticed that MEDPBY (actually MED_PSA) is pegging at 944. This may be because the sensor is maxed out or may be because the switched coax cables expect different voltages... or handle them differently or ... Must resolve this before RF01, and may have to back off on p set points to accommodate a lower MED_PSA (P drop across Valves 1, 3 get larger/worse at higher flows) 21:48:30 Pup crapped out at ~34100ft 21:50 Switched to low flow settings for high samples 22:16~ reset calint to 45, LS purging
